Original application filed July 8, 1919, Serial No. 243,917. Divided and this application filed April 18,

ect mixture of the oil and air before thev mixture enters the engine, and is especially effective when heavy oils which are more diilicult to mix are supplied to the carburetor, such oils being liable to separation from the mixture when passing :from the carburetor to the engine.

A further object of my invention is to provide a device which may be mounted in different positions with respect to its intake and outlet ports, without impairing its efficiency, in order that it may be readilj)T and conveniently applied to engines out various makes.

Other objects will be more fully disclosed in the following description, will be pointed out in the claims, and will be embodied in the accompanying drawings, in which:

Fig. 1 is a sectional view through a casing embodying my invention.

Fig. E2 is a similar view showing the casing as placed in a diii'erent position to that of Fig. 1.

My device comprises a suitable casing 5, preferably formed of a casting, and provided with a mixing chamber 6 having a water jacket 7 -formed therearound. The casing 5 is provided with a passage 8 through which the gas Jtrom the engine carburetor (not shown) enters the chamber 6, and a port 9 through which the re-mixed gas charge passes to the gas intake manifold 10 of the engine.

The chamber 6 consists ot a semi-annular passage 11 which increases in area from its intake end to its discharge end in order that the gases will expand and a centrifugal action will set u upon the iiuid passing therethrough, said discharge end communicating with the suction port 9 which is of.

Serial No. 462,42).

lesser area than the same, and a dead air pocket 12 formed in chamber 6 which is separated from intake passage 8 by a wall or battle plate 18. A narrow passage 14 is formed in the wall 13 to provide communication between the discharge end of the annular passage 11 and the inner end or" intake passage 8.

The gas intake end oi'passage 8 is contracted to form a throat as at 15 in order that the velocity of the gases passing intol said passage past the passage 1li will be iucreased, and a gas admission regulating valve 16 may be interposed between passage 8 and the carburetor as shown in 1 of the drawings.

A circulation of a heated fluid in the jacket 7 may be had through the pipe connections 17 and 18, in order to heat the mixing chamber to aid inthe volatilization of the gases.

In the operation of my device, suctionf is created in the usual manner, by means of.

the piston of the engine, which causes the gas mixture to be drawn 'from the carburetor through the passage 8 thence through the semi-annular passage 11 out through the port 9 to the engine cylinder. As the mixture passes through passage 11 with a whirling motion itis allowed toexpand and become separated, the heavier or more volatilized particles of the Oil are thrown by centrifugal action outwardly toward the outer surface of the wall of passage 11, and substantially tangent thereto, and by momentum and gravity are thrown against the wall 13, the lighter and more thoroughly mixed portions o the vaporized mixture passing through the port 9 to the engine cylinders to perform its usual function. As the mixture from the carburetor passes by the contracted portion 15 of passage 8, it increases in velocity thereby acting to suck the heavier particles of the mixture which have accumulated on wall 13 through passage 14 together with a portion ci." the gaseous mixtures passing through passage 11, to again be whirled through said passage and be broken up and become more volatile and intimately mixed.

When the device is assembled with respect to the engine and carburetor to assume the position shown in Fig. 1, the top surface of the wall 13 is inclined downwardly and in- When it is desired to vassemble the-device in a position such as is shown in Fig-2 of the drawings the breaking up of the heavy particles of the oil and the remixing operation is substantially the same as that above described,A the heavy oil particles being thrown against the wall 13 and that portionoi the same which is not at once drawn throughlthe-passage,14:, dripping downwardly into chamber 12 through a channel 20 formed in the-casing casting and thence to the passage Sto be again mixed with vthe incoming vapory and broken up as vpreviously described.

In the drawings thegeneral` direction of the low of the particles ot the mixture is indicated by thewarrowsythe arrow A indicatingthe volatile or light gases, the y-arrow B indicating the heavy particles or less'volatile partof the gases and the arrow C thedirection of the` frases and heavy particles of the mixture t roughv the passage `111- to becomere-mixed withthe, incoming gases from the carburetor.

That I claim is:

1. A. gas mixing device, comprising a case,

ing .provided with a semi-annular passage communicating at one ot its ends with an intake passage and at its other endwithaA i dischargefport, said semi-annular passage having its ends connected by la communicating passage of smaller `area than the areaAv thereof.

2. A gas mixing device, comprising a cas-` and l passing ing connected to said dead air pocket by a communicating passage of smaller area than said semiannular passage.

3. A -gas rmixing device, comprising a casing provided with a semi-annular passage communicating at one of its ends with an intake passage and at its other end with a discharge port and a dead air pocket7 said semi-annular passage increasing in area from its intake end to its discharge end, the

intake end of said semi-annular passage being connected to saidvdead air pocket by a communicating passage located at the vintersection of said intake passage 4andthe intake end of said semi-annular passage.

4. A gas mixing device, comprising `a casing provided with a semi-annular passage communicating at oneo'li its ends with an intake passage and at its other end with a discharge port, said semifannular passage having its ends connected -by a lcomrnimicatingpassage of smaller area than the area thereoil and saidintake passage being contracted to form a throat adjacent its outer end.

5. A gas mixingdevice, comprisinga cas. ing provided with asemi-annular passage communicatingat one of its ends withan intake passage and at its other end vwith aI discharge port and a dead air pocket, saidy semi-annular passage having its ends. conp nected by a communicating passage of `smaller varea ythanthe area thereof and said intake passage being contracted to form a throat adJacent its outer end, vsaid dead. air

pocket lhaving a drain port communicating therefrom to said intake `passage adjacent its outer end.

In witness that I claim the foregoingI have hereunto subscribed my yname this 5th day Aof April, 1921. y
